Something else you won't see on any NASCAR sites.  I am trying to find pictures of the different makes and models of cars that have raced in the CUP series.  A few models were raced, then not raced, then make a comeback. I've listed both if that is the case. Below is what I have been able to find
Info shows year, make and model of car pictured, driver of car, and years it was raced.
SO FAR I haven't been able to find any pictures of: Alfa Romeo; Austin Healey Sprite; Chrysler DeSoto; Plymouth Savoy; Buick Gran Sport; Buick Somerset; Chevrolet Baretta; Pontiac Tempest; MG-T Type; MG-MGA; Porsche 356; Triumph; Volkswagon and Willys.... but I'm looking
